Customer Service Department or by an appropriately qualified
specialist.
 Personnel operating the machine should be trained regularly.
Untrained personnel must not be allowed access to the machine or
its controls.
 Only use process chemicals which have been approved by their
manufacturer for the relevant application. The manufacturer of the
process chemicals is liable for any negative influences on the material
of the load and the machine.
 Take care when handling chemical agents. These may contain
irritant, corrosive or toxic ingredients.
Please observe the chemical agent manufacturer's safety instructions
and safety data sheets.
Wear protective gloves and goggles.
 The machine is designed for operation with water and
recommended additive chemical agents only. Organic solvents and
flammable liquid agents must not be used in it.

 Be careful when sorting items with pointed ends. Position them in
the machine so that you will not hurt yourself or create a danger for
others.
 Broken glass can result in serious injury when loading or
unloading. Broken glass items must not be processed in the machine.
 When using this machine in the higher temperature ranges, be
especially careful not to scald or burn yourself or come into contact
with irritant substances when opening the door. Where disinfecting
agents are used there is a danger of inhaling toxic fumes.

Warning and Safety instructions
16
 Should personnel accidentally come into contact with toxic
vapours or chemical agents, follow the emergency instructions given
in the manufacturer's safety data sheets.
 Mobile units, baskets, modules, inserts and the load must be
allowed to cool down before they are unloaded. Any water remaining
in containers could still be very hot. Empty them into the wash
cabinet before taking them out.
 Never clean the machine or near vicinity with a water hose or a
pressure washer.
 The machine must be disconnected from the mains electricity
supply before any maintenance or repair work is carried out.
Quality assurance
The following points should be observed to assist in maintaining
quality standards when processing laboratory glassware and
utensils to avoid damage to the loads being cleaned.
 If it is necessary to interrupt a programme in exceptional
circumstances, this may only be done by authorised personnel.
 The standard of cleaning and disinfection must be routinely
confirmed by the user. The process should be validated on a regular
basis, and checked against documented control results.
 For thermal disinfection, use temperatures and temperature holding
times to achieve the required infection prophylaxis in accordance with
current health and safety regulations.
 Make sure items being washed are suitable for machine
reprocessing and are in good condition. Plastic items must be
thermally stable. Nickel plated items and aluminium items can be
machine processed using special procedures only.
Items containing iron, and soiling containing residual rust must not be
placed in the cabinet.
 Chemical agents can, in certain circumstances, cause damage to
the machine. Always follow the recommendations of the chemical
agent manufacturer.
In case of damage or doubt about compatibility, please contact
Miele.
 Cleaning agents containing chlorine can damage the elastomers of
the machine.
If the use of cleaning agents containing chlorine is required, a
maximum temperature of 75°C in the “Main wash” programme
phases is recommended (see programme chart).
Cleaning agents containing chlorine must not be used in machines
supplied (ex works) with special oil-resistant elastomers for oil and
grease applications.

Warning and Safety instructions
17
 Abrasive substances must not be placed in the machine as they
could cause damage to the mechanical components of the water
supply. Any residues of abrasive substances on items to be washed
must be removed without trace before reprocessing in the machine.
 Pre-treatments with cleaning or disinfecting agents can create
foam, as can certain types of soiling and chemical agents. Foam can
have an adverse effect on the cleaning and disinfection result.
 Processes must be set up such that foam cannot escape from the
wash cabinet. It would hinder the correct functioning of the machine.
 The process used must be monitored on a regular basis by the
supervisor to check foaming levels.
 To avoid the risk of damage to the machine and any accessories
used with it caused by chemical agents, soiling and any reaction
between the two please read the notes in “Chemical processes and
technology”.
 Where a chemical agent is recommended on technical application
grounds (e.g. a cleaning agent), this does not imply that the
manufacturer of the machine accepts liability for the effect of the
chemical on the items being cleaned.
Please be aware that changes in formulation, storage conditions etc.
which may not be publicised by the chemical manufacturer, can have
a negative effect on the cleaning result.
 When using process chemicals, always consult the instructions
issued by individual manufacturers. Process chemicals must only be
used for the purpose they are designed for by the manufacturer to
avoid any material damage or the occurrence of very strong chemical
reactions (e.g. oxyhydrogen explosion).
 Always follow the relevant manufacturer's instructions on storage
and disposal of chemical agents.
 In critical applications where very stringent requirements have to
be met, it is strongly recommended that all the relevant factors for the
process, such as chemical agents, water quality etc. are discussed
with the Miele Application Technology specialists.
 If the cleaning result is subject to particularly stringent
requirements, e.g. in chemical analysis, the operator must carry out
regular quality control to ensure that required standards of cleanliness
are being achieved.
 The mobile units, baskets, modules and inserts that hold the load
must be used only as intended.
Hollow items must be thoroughly cleaned, internally and externally.
 Secure small and light items with cover nets or place in a mesh
tray for small items, so that they do not block the spray arms.
 Empty any containers or utensils before loading them.

Warning and Safety instructions
18
 The amount of residual solvents and acids on items going into the
cabinet should be minimal.
There should be no more than a trace of any solvents with a flash
point of below 21°C.
 Chlorous solutions, in particular hydrochloric acid, must not be
placed in the cabinet.
 Ensure that solutions or steam containing chlorides or hydrochloric
acid do not come into contact with the stainless steel outer casing of
the machine in order to avoid any damage through corrosion.
 After any plumbing work the water pipework to the machine will
need to be vented. If this is not done, components can be damaged.
 The gaps between a built-in machine and adjacent cabinetry must
not be filled e.g. with silicone sealant as this could compromise the
ventilation to the circulation pump.
 Follow the installation instructions in the operating and installation
instructions.
Safety with children
 Children must be supervised in the vicinity of the machine. Do not
allow children to play with the machine. They could get locked inside
it.
 Children must not use the machine.
 Keep children away from chemical agents. These can cause
burning in the mouth, nose and throat if swallowed, or inhibit
breathing. Keep children away from the machine when the door is
open. There could still be residual chemical agent in the cabinet.
Observe the safety data sheets for the chemical agent and seek
medical advice immediately if a child has swallowed chemical agent
or got it in the eyes.
Use of components and accessories
 Only Miele accessories should be connected to this machine. They
must be suitable for the application they are required for. Consult
Miele for details on the type of accessories that can be used.
 Only use Miele mobile units, baskets, modules and inserts with this
washer-disinfector. Using mobile units, baskets, modules and inserts
made by other manufacturers, or making modifications to Miele
accessories can cause unsatisfactory cleaning results, for which
Miele cannot be held liable. Any resultant damage would not be
covered by the guarantee.
